Abstract

"PROCESSO PARA O RASTREAMENTO DE CHAMADA EM UM SISTEMA DE REDE DE NóS, SISTEMA DE REDE PARA O RASTREAMENTO DE CHAMADA, EXTENSãO DE PROTOCOLO PARA GRAVAR UM CAMINHO DE UMA CONEXãO EM UM SISTEMA DE TELECOMUNICAçõES, COMANDO ELETRONICAMENTE EXECUTáVEL EM UMA MEMóRIA, PROCESSO PARA O RASTREAMENTO DE CHAMADA EM UM COMUTADOR DE TELECOMUNICAçõES, E, COMUTADOR DE TELECOMUNICAçõES PARA RASTREAMENTO DE CHAMADA" Um processo e sistema de Rastreamento de Chamada de Rede (NCT) permite uma rota de caminho de chamada a ser rastreada em uma rede de telecomunicações. Um Tipo de Dígito (TOD) no Parâmetro de Dígitos Genéricos (GDP) para um comando de Parte de Usuário (ISUP) da Rede Digital de Serviços Integrados (ISDN) pode ser utilizado para realizar a NCT. Uma listagem das IDs de Comutador (SIDs) do comutador de assinante de origem para o comutador de assinante de destino é fornecido de forma que as ineficiências de encaminhamento podem ser descobertas. Em uma modalidade, uma Mensagem de Endereço Inicial (IAM) é transmitida com um Rastreamento de Chamada de Rede TOD no GDP. O NCT inclui a SID do comutador de origem. Quaisquer comutadores intermediários entre o comutador de origem e o comutador de destino anexam da mesma forma sua própria SID na lista NCT das SIDs. Finalmente, o comutador de destino também soma sua SID no fim da lista NCT. Essa lista NCT pode então ser transmitida e exibida para análise. Por exemplo, pode ser transmitida em uma mensagem de retorno tal como a mensagem de endereço completo (ACM), a mensagem de resposta (ANM), chamada em andamento (CPG), ou liberação (REL) de volta para o comutador de origem através da rede. Alternativamente, a lista NCT pode ser enviada para um Centro de Gerenciamento de Rede."PROCESS FOR CALL TRACKING IN A NODE NETWORK SYSTEM, NETWORK SYSTEM FOR CALL TRACKING, EXTENSION OF PROTOCOL TO RECORD A PATH OF A CONNECTION IN A TELECOMMUNICATIONS SYSTEM, COMMANDING AN ELECTRONICALLY EXECUTIVE OPERATION, IN AN EXECUTIBLE PERFORMANCE. CALL TRACKING ON A TELECOMMUNICATIONS SWITCH, AND, TELECOMMUNICATIONS SWITCH FOR CALL TRACKING "A Network Call Tracking (NCT) process and system allows a call path route to be traced on a telecommunications network. A Digit Type (TOD) in the Generic Digit Parameter (GDP) for a User Part (ISUP) command of the Integrated Services Digital Network (ISDN) can be used to perform the NCT. A listing of Switch IDs (SIDs) from the source subscriber switch to the destination subscriber switch is provided so that routing inefficiencies can be discovered. In one embodiment, an Initial Address Message (IAM) is transmitted with a TOD Network Call Tracking on GDP. The NCT includes the SID of the source switch. Any intermediate switches between the source switch and the target switch likewise append their own SID to the NCT list of SIDs. Finally, the destination switch also adds its SID to the bottom of the NCT list. This NCT list can then be transmitted and displayed for analysis. For example, it can be transmitted in a return message such as the full address message (ACM), the reply message (ANM), call in progress (CPG), or release (REL) back to the originating switch via from the Web. Alternatively, the NCT list can be sent to a Network Management Center.
